Beams with an intermediate pier: Spectral properties, asymmetry and stability

open access: yesMathematics in Engineering, 2021
We deal with beams with an intermediate pier, motivated by the investigation of the stability of suspension bridges with two spans. First, we provide a complete spectral theorem for the associated linear stationary fourth-order problem with hinged ...

Higher-order moments and overlaps of Cartesian beams [PDF]

open access: yes, 2010
We introduce a closed-form expression for the overlap between two different Cartesian beams. In the course of obtaining this expression, we establish a linear relation between the overlap of circular beams with azimuthal symmetry and the overlap of ...

Paroxysmal hemicrania as the clinical presentation of giant cell arteritis

open access: yesClinics and Practice, 2011
Head pain is the most common complaint in patients with giant cell arteritis but the headache has no distinct diagnostic features. There have been no published reports of giant cell arteritis presenting as a trigeminal autonomic cephalalgia.

The coherent beam-beam interaction [PDF]

open access: yesConference Record of the 1991 IEEE Particle Accelerator Conference, 2002
The authors present the results of a new beam-beam simulation program that allows for a self-consistent calculation of the electromagnetic fields of the beams by treating general (non-Gaussian) beam distributions. The simulation program calculates the fields from the coordinates of the test-particles, and does not impose any restrictions on the beam ...

Paraxial skyrmionic beams

open access: yesComplex Light and Optical Forces XV, 2020
We show that a class of vector vortex beams possesses a topological property that derives both from the spatially varying amplitude of the field and also from its varying polarization.

Numerical investigation of steel-concrete composite beams using flexible shear connectors

open access: yesAIMS Materials Science, 2022
This paper focuses on the investigation of the flexural behaviour of steel-concrete composite beams through non-linear finite element analysis. Both geometries, as well as material non-linearity, are considered.

Influence of section depth on the structural behaviour of reinforced concrete continuous deep beams [PDF]

open access: yes, 2007
YesAlthough the depth of reinforced concrete deep beams is much higher than that of slender beams, extensive existing tests on deep beams have focused on simply supported beams with a scaled depth below 600 mm.

Test Beams and Polarized Fixed Target Beams at the NLC [PDF]

open access: yes, 2001
A conceptual program to use NLC beams for test beams and fixed target physics is described. Primary undisrupted polarized beams would be the most simple to use, but for NLC, the disrupted beams are of good enough quality that they could also be used ...
